Various standardized numbers have also been created for special services, for example, area code 800 for toll-free service, and 911 for emergency service.

A special numbering plan is also used within the MERLIN LEGEND Communications System to identify individual telephones, adjuncts (for example, fax machines), trunks, and other features and aspects of the system. Depending on the number of extensions and the needs of your company, you can choose from three different numbering plans that allow 2-digit numbers, 3-digit numbers, or customizable variable-length numbers, respectively.
